Add a new shader-versioning infrastructure capable of handling multiple profiles, desktop/ES, many versions, features coming and going in different versions across different profiles, and extensions.

NB: *Use* of this infrastructure is so far only skeletal.

Fixed a few typos and minor issues along the way.
